To all whomy t may concern.' shell and the plate A which isA suitably Be it known that I, JOHN BERG, a citisecured tosaid end wall. 55 zen of the United States, residing at The cup B, may be formedby a suitable Chicago, in the county of Cook-and State drawing operation from a. thin sheet metal of Illinois, haveinvented a new and usedisk. The end wall B2, which constitutes ful Improvement in Switch Devices, of the bottom of the cup. may be secured to which the following is a specification. the plate A in any suitable manner. In 60 This invention relates particularly to a the illustration given, said bottom wall is switch device, or circuit-closing device, spotewelded to the plate at points desigwhich is particularly useful in connection -nated 1.

The extremity of this member 6h is provided with aflu 6c which enters a recess 8 with which the isk D is provided on its inner surface.

The web-portion 6, of the spring member E, is preferably curved to somewhat ka proximate an-arc having asits center t e center. about which the lever F swings. However, the arran ement is such that when the lever is swung' rom the dotted position shown in Fig. 5, to the full osition shown in Fig. 4,tlie inner end of t e lever, which is provided *withl an insulation Ypoint 9, will ride on the web-portion 6 of the member E and force the member tothe circuit-closing position.
